Product Manager II - Software & Communications

About the role Muon Space is hiring a Product Manager to own how much data our missions get to the ground, and how we prove it. Reporting to a Director of Product Management, you will own bits-to-ground communications across RF and optical links, simulation, and software test. This position is hybrid and requires working on-site in our San Jose, CA office four days per week. Responsibilities Comms, Simulation and Test • Own the product roadmap for bits-to-ground communications across RF and optical (OCT) links. • Own the product roadmap for Muon Sim, the digital twin behind mission design and mission operations, including the throughput analysis that sets what a constellation can deliver. • Grow simulation into a tool for software iteration, so flight and ground software can be exercised against the twin before it reaches a spacecraft. • Own the product roadmap for software test infrastructure, automation, and hardware-in-the-loop environments. • Define and prioritize features that improve product quality, schedule adherence, or customer value. • Author clear Product Requirements Documents (PRDs), drive alignment, and follow through reliably. • Partner with the Director of Product Management to develop the strategy for the product areas including build/buy decisions. • Conduct customer interviews, gather feedback on product–market fit, and translate insights into roadmap decisions. Cross-functional Coordination • Partner closely with engineering teams across ground software, simulation, test, and mission systems to define features and roadmap. • Partner with other software product managers on roadmaps where capabilities intersect. • Coordinate with the Director of PM — Federal on defense-aligned product needs and inputs to roadmap. • Collaborate with the VP of Product and the broader PM team on strategic roadmap decisions and prioritization trade-offs. Required Qualifications • 3–5 years of Product Management experience, with demonstrated success owning software products in technically complex environments. • Experience in communications systems, simulation, test infrastructure, or adjacent deep-tech software domains. • Experience working cross-functionally with multiple engineering teams at once, rather than a single team. • Demonstrated success in uncertain environments with incomplete requirements and shifting schedules. • Proven track record delivering major features or programs spanning multiple months of effort. • History of independent execution and implementation across multiple concurrent workstreams. • Strong fluency working with engineering peers and leadership; able to influence cross-organizational technical investment without direct authority. • Demonstrated ability to translate customer mission needs into detailed product requirements and acceptance criteria across software systems. • Bachelor's degree in Engineering, Computer Science, or a related technical field; advanced degree preferred. Nice-to-have Skills • Active U.S. Government security clearance. • Familiarity with RF or optical communications, link budgets, or ground station networks. • Familiarity with mission design, constellation modeling, or digital-twin platforms across orbit, power, and data delivery. • Familiarity with test automation or hardware-in-the-loop test environments. • Familiarity with building or operating software for the space environment. • Prior experience in startup or high-growth technology environments. Salary The salary range for this role is $177,000 - $203,000, plus a competitive equity grant and comprehensive benefits package. Final compensation will be determined based on skills, qualifications, experience, and geographic location as assessed during the interview process.
